I’ve got a YouTube pal in England who is putting out some great instructional videos for acoustic blues. His name is Jim Bruce and he teaches the real shit – like it was played on the recordings of Blind Blake, Tampa Red, Scrapper Blackwell, and many others. If you are interested in this kind of blues guitar – check out his site.
Jim Bruce is great. I’ve had all his lessons for about a year. He breaks each song down with video and tab and makes it all very accessible. He’s also great marketing his product.
